How can a CNA help decrease the side effects of respiratory changes as clients age?

Positioning the client in a semi-Fowler’s upright position is effective in promoting better respiratory function as it aids in lung expansion and increases oxygenation. This position allows for improved diaphragm movement, which can alleviate shortness of breath and enhance comfort, especially in older adults who may experience decreased lung capacity and diminished respiratory efficiency.

Though the other choices may also have some merit in managing respiratory discomfort, they do not directly address the improvement of lung mechanics and oxygenation as effectively as proper positioning does. For example, deep breathing exercises can be beneficial, but they may not always be feasible for clients with significant respiratory distress. Increasing room humidity can help with symptom relief, but it does not offer the support for lung mechanics that positioning does. Providing less physical activity may prevent fatigue but does not encourage the use of the respiratory system, which is essential for maintaining lung health and function. Therefore, positioning the client correctly stands out as the most effective method to help decrease the side effects of respiratory changes in aging clients.
